There’s nothing that kills a good day on the trail faster than a sudden loss of power. You’re cruising along, and then—bam—your rig bogs down, the check engine light glares at you, and you’re stuck in limp mode. If you’ve pulled the codes and found 18 polaris 900 xp code 65613, you’re in the right place.
We know how frustrating that can be. But don’t start thinking about a massive repair bill or a long wait at the dealership just yet. This error, often related to your throttle control system, is one of the most common problems with the Polaris 900 XP, and it’s frequently something you can diagnose and fix right in your own garage.
This complete guide will walk you through exactly what this code means, the most likely culprits, and a step-by-step process to get you back to full power. We’ll cover everything from simple checks to more in-depth diagnostics, giving you the confidence to tackle this head-on.
What Exactly is Polaris Code 65613? Decoding the “Throttle Release Error”
At its core, code 65613 (along with its partner codes 65614 and 65615) points to a problem within the Electronic Throttle Control (ETC) system. Think of the ETC as the digital messenger between your foot on the gas pedal and the engine’s throttle body.
When you press the accelerator, a sensor tells the Engine Control Unit (ECU) how far you’ve pushed it. The ECU then commands a motor on the throttle body to open the butterfly valve a corresponding amount, letting air into the engine.
Code 65613 is triggered when the ECU sees a disagreement. Most often, it means the system detects that both the throttle and the brake are being applied at the same time for too long. To protect you and the machine, the ECU cuts power and puts the vehicle into limp mode. While driver habit is one cause, this error more commonly points to a faulty sensor or wiring giving the ECU bad information.
The Usual Suspects: Common Problems Causing Code 65613
Before you start throwing parts at your Polaris, let’s narrow down the likely culprits. Based on our experience in the shop, this code almost always traces back to one of a few key areas. Understanding these common problems with 18 polaris 900 xp code 65613 is the first step to a successful repair.
The Accelerator Pedal Position Sensor (APPS)
This is the sensor attached to your gas pedal assembly. It’s the first link in the chain, and it’s exposed to mud, water, and vibration. If this sensor starts to fail or has a bad connection, it can send erratic signals to the ECU, causing the error.
The Dreaded Wiring Harness
Frankly, this is the number one cause we see. The wiring harness on Polaris machines, especially the one connecting the gas pedal to the main ECU, is prone to rubbing, chafing, and breaking. A single exposed or broken wire can create a short or an open circuit, fooling the ECU into thinking there’s a problem with the pedal.
Brake Pedal Switch Issues
Since the code is directly related to a brake/throttle conflict, a faulty brake light switch can be the offender. If the switch is stuck “on,” the ECU thinks you’re constantly on the brakes, and the moment you touch the gas, it throws the code.
Low Battery Voltage
Never underestimate the power of a good battery. Modern UTVs are packed with sensitive electronics. If your battery voltage is low, sensors can send incorrect readings, leading to a host of phantom error codes, including 65613.
Your DIY Toolkit: Gear Up for the Diagnosis
You won’t need a full professional shop to tackle this job. A few basic tools will get you through most of the diagnostic steps. Here’s your essential checklist:
- Digital Multimeter: This is non-negotiable for testing sensors and checking for continuity in wires.
- Basic Socket and Wrench Set: For removing panels and components.
- Torx Bit Set: Polaris loves Torx fasteners.
- Flashlight or Headlamp: Good lighting is crucial for inspecting wiring.
- Contact Cleaner: To clean up grimy electrical connectors.
- Dielectric Grease: To protect those clean connections from moisture and corrosion.
How to 18 Polaris 900 XP Code 65613: Your Step-by-Step Diagnostic Guide
Alright, let’s roll up our sleeves and get to work. Follow this 18 polaris 900 xp code 65613 guide methodically. Do not skip steps, as the simplest thing is often the solution.
Safety First: Before you begin, park your vehicle on a level surface, put it in park, and turn the ignition off. We recommend disconnecting the negative battery terminal to prevent any accidental shorts.
Step 1: The “Brake Stomp” Reset
Sometimes, the ECU just needs a little reset. It’s a long shot, but it’s free and takes 30 seconds. This procedure can sometimes recalibrate the throttle pedal’s zero and full-throttle positions.
- Turn the key to the “ON” position, but do not start the engine. Wait for the fuel pump to prime and the dash to cycle.
- Slowly and smoothly press the gas pedal all the way to the floor.
- Slowly and smoothly release the pedal completely.
- Repeat this process two more times for a total of three full, slow presses.
- Turn the key off. Wait 10 seconds, then start the engine and see if the code has cleared.
Step 2: A Thorough Wiring Inspection
This is where you’ll likely find your problem. Grab your flashlight and get ready to play detective. You’re looking for the wiring loom that runs from the gas pedal assembly up toward the front of the machine and back to the ECU.
Pay extremely close attention to these areas:
- Behind the gas pedal: Wires can get pinched or stretched here.
- Where the harness passes through the firewall: Look for sharp edges that could have cut into the loom.
- Along the frame rails: Check any point where the harness is secured with a zip tie or clip. These can rub through the insulation over time.
- Near the front differential: This is a notorious spot for rubbing.
If you find a damaged section, you’ve found your culprit. You’ll need to carefully cut away the loom, repair the broken wire(s) using a good quality butt connector with heat shrink, and then re-wrap the area with electrical tape or a new loom for protection.
Step 3: Clean and Secure Your Connections
If the visual inspection doesn’t reveal any damage, the next step is to check the electrical connections. Unplug the connector at the gas pedal and the main connector at the ECU.
Inspect the pins and sockets for any signs of corrosion (green or white powder), dirt, or moisture. Spray both sides of the connection liberally with contact cleaner and let it air dry completely. Before reconnecting, apply a small amount of dielectric grease to the seal to keep moisture out. Ensure the connectors click firmly back into place.
Step 4: Test the Brake Light Switch
With the key on, have a friend stand behind the vehicle. Press and release the brake pedal. Do the brake lights turn on and off crisply? If they stay on, are dim, or flicker, you may have a faulty or misadjusted brake switch, which could be sending a constant “brake on” signal.
18 Polaris 900 XP Code 65613 Best Practices and Care Guide
Once you’ve fixed the issue, you’ll want to prevent it from coming back. Adopting a few best practices into your routine can make a huge difference. This is a core part of any sustainable 18 polaris 900 xp code 65613 care guide.
Proactive Wire Protection
Go back to those common chafe points we mentioned. Even if your wires aren’t damaged yet, add some extra protection. Use split-loom tubing or a durable wrap like Tesa tape around vulnerable sections of the harness. A few well-placed zip ties can also keep the harness from sagging or rubbing against moving parts.
Maintain a Healthy Battery
Regularly check that your battery terminals are clean and tight. If you don’t ride often, use a battery tender to keep it fully charged. A healthy electrical system is the foundation for reliable sensor performance. This is an eco-friendly 18 polaris 900 xp code 65613 tip, as it extends battery life and prevents waste.
Mind Your Feet
Avoid “two-footing” your Polaris—that is, resting one foot on the brake while accelerating with the other. This driving style is the direct cause of the code if no mechanical or electrical fault exists.
Frequently Asked Questions About 18 Polaris 900 XP Code 65613
Can I still ride my Polaris with code 65613 active?
You can, but it will be in limp mode, meaning significantly reduced power and speed. It’s designed to get you back to the truck or camp, not for a full day of riding. Continuing to ride with the code could potentially mask a more serious issue, so it’s best to diagnose and fix it promptly.
How much does it cost to fix code 65613?
The cost can vary dramatically. If it’s a simple wiring repair you do yourself, the cost could be less than $10 for supplies.
